The assignment partly includes parallel investigations and action preparations of the four source areas in order to develop proposals for the technically, environmentally and economically best choices of action technologies for each source area.

In existing action investigation for the object, soil mixing for the addition of chemical oxidizer, thermal treatment with steam injection and ISTD, stimulated natural self-purification (aerobic), and containment have been investigated. Through subsequent risk assessment, soil mixing was recommended for chemical oxidation and thermal treatment of the steering group. In the current assignment, other possible methods will also be investigated, such as injection of chemical oxidizers and excavation/large-diameter drilling. No specific treatment tests in e.g. bench scale or pilot tests on site have been performed so far.
